Specification of Letters Patent.

Patented April 21, 1908.

Application filed. February 2, 1907. Serial No. 355,495.

To all whomjt may concern:

Be it known that I, CHARLES E. STosE, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in WindowConstruction, of which the following is a specification. This inventionrelates to windows and more especially to railway coach windows, and myobject is to produce a window which will be perfectly air tight and inwhich the sash can be easily and quickly raised or lowered.

A further object is to produce means for locking the window against anyattempt to raise it prior to the withdrawal of one of the jambs from theopposing edge of the sash.

With these objects in view and others as hereinafter, appear theinvention consists in certain novel and peculiar features ofconstruction and organization as hereinafter described and claimed; andin order that it may be fully understood reference is to be had to theaccompanying drawings, in which Figure 1, is a horizontal section of awindow embodying my invention. Fig. 2, is a vertical section on the lineIIII of Fig. 1. Fig. 3, is a horizontal section on the line IIIIII ofFig. 2. Fig. 4, is a perspective view on a reduced scale of the casingfor the movable jamb forming a part of the invention. Fig. 5, is a viewsimilar to Fig. 1 of a modified form of construction. Fig. 6, is a viewtaken on the dotted line VI of Fig. 5 but on a smaller scale. Fig. 7, isa view taken on the line VIIVII of Fig. 5. Fig. 8, is a vertical sectionon the same scale as Fig. 5, and on the line VI thereof.

In the said drawings where like reference numerals indicate the sameparts in all the figures, 1 indicates a window frame, 2 the uprights,ordinarily called the jambs, 3 the inner stops, 4 the outer stops, and 5the sash, the vertical corners of the latter being cut away to providethe converging edges 6 to fit snugly against the corres ondinglyinclined inner walls of metallic ribs 7 between the stops, said ribsbeing preferably united by central portions 8. For convenience ofattachment the ribs 7 at one side of the sash are provided with flanges9 fitting between the uprights 2 and the stops 3 and 4 and secured tothe uprights by wood screws 10 or equivalent devices, the ribs 7 forminga jamb of eculiar shape and bearing a wedge-like reation to the sash.The ribs 7 at the op osite side of the sash have their outer wa ls ofgreater width by preference than the corresponding walls of the amb atthe firstnamed side, and said walls fit slidingly against the innersurface of a metallic casing 11 fitting in a recess 12 in the juXta osedupright 2, said casing having lateral y projecting flanges 13, whichproject from its front edges and are held between said upright 2 and thestops 3 and 4. The casing is also preferably provided with end walls 14as a convenient support for eye-bolts or hooks 15.

At a suitable point the side walls of the casing areprovided withcircular holes 16 to form bearings for the horizontal shaft 17 extendinginwardly through the upright 2, and terminating by preference in asquared end as at 18, engaged by a corresponding socket in the stem 19journaled in the casing and having its outer end reduced and journaledin a bearing 20 secured to the casing and secured upon the inner end ofsaid reduced portion of the stem is a handle 21 by which the stem 19 andshaft 17 can be turned when desired.

22 indicates a disk secured rigidly on shaft 17 centrally of the casingin any suitable manner and pivotally connected to said disk atdiametrically opposite points and extending in opposite directionstherefrom are links 23, the remote ends of the links being pivotallyconnected to reciprocatory bars 24 provided with cam or inclinedportions 25 drawn longitudinally apart by springs 26 connecting the endsof said bars with the eyes of the hooks 15 of the casing. To insuredirect reciprocatory movement of bars 24 between the bifurcated brackets27 and 28, their outer and inner edges are engaged by anti-frictionrollers 29 carried by the brackets for the purpose of reducingfrictional resistance to the movement of bars 24 to the minimum.

As will be seen by reference to the drawing Sheet 1, the springs tend topull the lower rod downward and the upper rod upward and consequentlyrotate the shaft in the direction indicated by the arrow Fig. 2. izethis power of the springs to secure the To util-- sash in the casingwith an air tight relation or to clamp it reliably at any desiredheight, themetallic portion 8 of the movable j amb fitting in the casingis provided with a pair of brackets 30 equipped with rollers 31 engagingthe outer and inner edges of the cam portions of bars 24. By thisarrangement it will be seen that as the cam portion of the upper barmoves upward and the corresponding portion of the lower bar moves down-Ward simultaneously, they force the jamb equipped with saidanti-friction rollers 31 against the edge of the window sash, thestrength of the springs being sufficient to hold the sash reliably atany point of adjustment and it Wilbbe noticed by reference to Figs. 1and 3 that under such pressure the inclined portions of the ribs 7establish an air tight joint with the correspondingly beveled edges ofthe sash it being noted that the portion 8 of the jamb does not engagethe sash 2, and therefore does not prevent the ribs from being pressedheavier against such beveled edges.

When it is desired to adjust the sash the operator grasps handle 21 andturns it up and toward the left, this action through the medium of links23 pulling bars 24 endwise toward shaft 17 through the medium of the camportions 25 drawing the movable j amb away from the edge of the windowso that the latter may be permitted to descend. When the handle isreleased the springs 26 retract and pull the bars 24 away so that theircam portions shall again cause the movable jamb to press against theadjacent edge of the sash and not only establish an air tight joint withsaid edge but also between the edges at the opposite side of the sashand the stationary jamb. When the handle is turned as explained it isobvious that there is practically nothing more than the weight of thesash for the operator to.lift and that the same can be raised readilywith one hand and in fact on the ordinary cars the sashes are of suchsize that a child can readily raise them when thus released.

I contemplate equipping the stop 4 with a rubber or equivalent strip 32to provide an air tight joint between the casing 11 and the movable ambas shown in Fig. 1. To prevent a person from raising the sash withoutfirst turning the handle 21 properly, I provide means for locking thesash in its closed position, the same comprising a V-shaped arm 33pivoted to the lower bar 24 and ada ted to project through an opening 35in the movable jamb intoa recess 36 in the edge of the sash. Theopposite end of the pivoted arm is weighted as at 37 for the purpose ofholding the sharp end pressed against the portion 8 of the movable jamb,it being understood that the distance between the pivot and the point ofthe tooth 33, is considerably in excess of the distance between saidpivot and the portion 8 of the jamb. As a result of this construction anattempt to raise the sash must fail unless the lower bar 24 is firstmoved upward so as to raise the pivoted catch arm and at the same timepivotally operate it in the direction indicated by the arrow under thepressure upon' portions to force the movable jamb further away from thebars 24, the action of the arm described is reversed and it stands withits pointed end against or below the edge. of the sash according to theposition of the window and ready to swing into the recess 36 when thesash is again completely lowered. it will thus be seen that thismechanism is automatic and that the withdrawal of the jamb from the sashinstantly effects the unlocking of the latter. The construction above described is designed primarily to accommodate window constructions whichare in common use at present.

In Sheet 2, I show a construction as follows :38 indicates a cross pincarried by the. movable jamb and 39 a link pivotally secured to saidcross pin and extending upwardly through an opening 40 in the adjacentupright 2 and also through a registering opening 41 in a bracket 42bolted as at 43 to said upright, and provided with alined. bearings 44for the shaft 45 on which the outer end of the link 39 is pivoted. Theshaft between the bearings is eccentrically enlarged as at 46 and inthis connection it will be noticed that the bracket is in sections asotherwise it could not be fitted on the shaft at opposite sides of theeccentric and secured to said eccentric at opposite sides of the linkarea pair of stiff springs 47 which bear at their upper ends against theupper portions of the bracket.

At its inner end the shaft is squared as at 48 and said squared end isadapted to be engaged by mechanism corresponding to that shown in Sheet1 and correspondingly numbered, the )IGSSUIB of the springs 47 againstthe unyielding bracket 42 results in turning -the shaft in the directionindicated by the arrow Fig. 8 so as to tend to throw the eccentricportions of the shaft forward of its axis and thus cause the movablejamb to clamp against the sash as hereinbefore explained in connectionwith the first sheet of drawin In view of the height of the window it isnecessary to provide pressure at two or more points and for this purposeI interpose springs 49 between the movable jamb and the upright 2, thes)rings being secured at one end to the amb )y preference. By thusapplying spring pressure above and below the center of the jamb thelatter is main- '1 tained in its proper relation to the sash and willhave but little tendency to tilt as it would under the application ofpressure at only a single point nearer one end than the other. Bymanipulating handle 2]. so as to turn the shaft in the oppositedirection to that indicated by the arrow Fig. 8, the pressure of thesprings is overcome and the amb is pulled away from the window so as topermlt the latter to be adjusted in the manner explained.

The construction shown by Sheet 2 is intended primarily for use u oncars which have no vertical rods behin the uprights 2, and for carsequipped with such rods the construction shown on Sheet 1 is preferable,though it will also be apparent that the lastnamed construction isadapted for use upon cars equipped with windows of any type.

From the above description it will be apparent that I have produced awindow construction possessing the features of advantage enumerated andI wish it to be understood that I do not desire to be restricted to theexact details of construction shown and described as obviousmodifications will suggest themselves to one skilled in the art.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent, is
